Dear bike community,
my name is Artur, and I would like to present you new ebike project called Vector.
It was build by the team of entuziast in Ukraine, and soon will appear on kickstarter.
We would be very grateful if you could tell us what do you think about it.
We are interested to know what do you think about bike in general, it's components, look, price, everything you think is important.

Wow if you can get it to $5-6K USD that would put Stealth out of business! That is how much it cost me to build my 5KW ebike. Though it probably have a lot more battery capacity than this ebike.

Good luck and looking forward to the kick starter campaign!

Here is my recommendations:
1) can this be fitted with the Nissan leaf battery? For me it is critical because I can get it relatively easy and it is the cheapest safest batteries you can get now here is the states.

2) pricing around $5-6K for the full bike is killer price. It might even be disruptive to the industry. Decent ebike frames are $2-4K alone not counting the rest of the bike. So if you can get the whole bike to around that level with decent reliability, I think you have a solid product!

3) do sell the frame kit separately. I can assure you the market you are entering is a small market and most will want to put their own parts into it. This is not to say you cannot make money. Just know you have to beat everyone out to make it big.

4) is the rear dropout is 150mm? I see some of your prototype have the cromotor as the rear wheel. I think this is the motor to go to if you want high power and have a 150mm dropout. If it is not 150mm dropout, do offer one. If I do get the frame kit, I would definitely want to fit the cromotor to it.

5) kickstand? Maybe weld a simple kickstand to it? Or offer it as asscessoires. Just saying because not everyone have a wall to lean the bike on. This would be one of those wish list things. I would only pursue if you have the time and money.

6) front and rear fender? Mainly rear fender. I can definitely fit a decent fender on the boxxer fork. But the rear will be a challenge. If you have the funds to go do this research, I would go out and buy a commonly available after market fender and try to mount it, and make any mounts required to make it fit easily.

Thank you for your comment!

1. I dont know the size of nissan batterie. But I can show you measuring of bike batterie place.

I think those are all the comments I have for the ebike itself. The rest looks rock solid.

EDIT: a few more:
1) Get Tekro E-Hydraulic ebrakes. Still Hydraulic, but have built in reed sensor to engage regen. I think the button is a pretty crappy solution because when you want to brake you don't press a button. Also you would still have to press the brake lever if you do end up using it. To much of a hassle in my opinion. The other option might have beefier hydraulic brakes, but I would stick with the Tektro Hydraulics ebrakes for now

2) I would try to do something other than HK Lipo. I notice in your picture you use them. They are cheap and you can custom your battery size easily, but I don't know if it's for everyone. Also keep in mind you are dealing with HobbyKing (HK). They can screw you pretty easily. Also their stuff tend not to last as long so I would expect high servicing cost for you. I don't know of any legit ebike company selling their ebike with HK lipo. Too much of a fire risk factor for them apparently. The stealth Bomber is LiFePo4. Outrider is Li-Mn or safe Lipo. This one might be hard for you to solve because it's pretty difficult to get legitimate, low cost, long lasting, safe, and reliable Lithium battery. Good luck on this. Maybe you can do bulk buy to keep cost in check.

3) Lyen controllers are great starter controller. For more reliability and longevity, I would go with Kelly. But again maybe you will be offering them as options already.

The big key here is to get it reliable. You don't want to spend all your money servicing these suckers! This usually means over-enginnering the ebike, which increase cost which means the only realistic way you can make money is to either: Sell it for high price OR do economy of scale and bring the cost down for the parts. Or do a little of both like what Tesla is doing with their Electric Car.

Good luck on the campaign. I am looking forward to see what the pricing structure will look like.

Thank you for your message!

1. We were thinking about different kind of brakes. The thing is to convert some kinetic energy (speed) into potential (electrical charge) we need some amount of time during regenerative braking. We cant transfer kinetik energy of the bike into potential due to couple of reasons and the most important one is because batteries are not able to store fast very big portion of energy. Thats why during fast or emergency braking using bike brakes only small fraction of energy actually will return to bike battery. Usually regenerative braking work well during relatively slow braking (long hills). For this ebike we will offer 3 types of brakes, wire disc brakes, hydraulic disc brakes, and something similar to Shimano Saint hydraulic brakes system*(high-end).

2. This type of batteries is used for our prototypes. As you mentioned they are not "idiotproof" To our final versions we will use: 48V 20Ah LiFe battery, 72v 15AH LiFe A123 , 72V 24AH Life A123. All batteries will work with smart BMS.

3. We will offer different variants of controllers as well as motors for final products with Lyen and Kelly programable controllers. Many people who are new in ebike world dont look for 1kW+ bike , and for some people even 6kW is not enought )
The important thing is that advanced ebikers would be able to order frame only, to build their own ebikes!

I'm not a fan of the dual rear shock. Too much money when a simple spring upgrade will do. The frame looks nice and lighter than the Raptor. But that is just by just looking at it. The Raptor is a crazy strong setup though.
I like the fact that you can put the controller inside the frame.
Have you looked into the new 4 piston brakes offered by Magura?

Will you offer the battery separate from the frame to the general public?

Appreciate your comment Snellemin,

dual rear shock was just a option for people who can not afford 1 high-end rear shock ( maybe even from pit bike), so in this case 2 less expensive shocks can help. But as I mentioned it is just a option.

The frame weight now is around 9kg. It is strong anough to handle all terrain. Here is some tests )

Yes controller located inside. Due to ventilation wholes air cool down all electronic components and at the same time controller and all wires are protected from rocks, dirt and falling.

Plus on a frame we have 2 USB ports 1A and 2A for charging phones not worring having a dead GPS battery in a forrest. Also frame goes with 8*Cree diode light, using bike battery power.

I agree with snellemin, the dual shock looks odd and isnt really necessary. You've saved weight elsewhere, it's silly to waste it on a second shock.
I like the carbon bits and the little 'window' in some of the pics higher up looks good to break up the frame. I think it could do with being bigger or there some other stickers or something to break up the otherwise fairly stark big broad area of sheet.

Nice to see some other options for purpose built ebike frames emerging. I'm sure more of the DIY crowd here would be keen to know what you plan to sell a bare frame for.
I'm curious why you're going to kickstarter as it seems you already have a bunch made. Is it to cover the capital to buy all the components to build whole turnkey ebikes ?

Thank you for your comment!

The small "window" on a frame is made for LCD screen that will show battery info (% of charge, voltage, temperature of battery, cell voltage, amps usage...)
Next to it will be two USB charging port and CA as option.

We want to paint side covers with custom graphic as option, to make each bike frame unique.

Oriented price of the frame will be 700-800$ plus delivery.

We want to start kickstarter campaign with 3-5 basic components complications for wide public. Starting with comparatively cheap components for city use, finishing with top-end components for wild off-road. As not many people have time to order components to build e bike by himself.
But we also would offer frame for those who want to build bike by himself.

Hyena is asking why not just sell on your website instead of going through kickstarter. Unless you plan to use it as an advertising engine. I agree with hyena that it seems like you got the production down.

Most people go on kick starter because they need the money for the tooling required to get to economy of scale for some decent returns.

Either way would be OK with me. But just know kick starter takes a cut and amazon takes a cut too I think. So you won't get the full value with kickstarter. But think of the cost as advertising cost. : )

Good luck. Looks Luke you might want to update some of your technical information base on some chances since then.

Thank you mvly,

I know about kickstarter and amazon fee.. But as a first push to get publicity there is no better option for this % of money. Even if we will not raise the funds we expect we still get our clients on a our web site, where they can buy Frame or Whole bike.
Even with kickstarter fees price of the bike with better performance and complectation will be 20-35% lower then Stealth..
We need those money for ordering all bike components in big number under lower price.
